Abstract

sistemas, métodos e aparelhos para configurar um sensor de impressão digital para operar em um modo de detecção capacitiva e em um modo de detecção ultrassônica. um sensor de impressão digital pode ser configurado para operar em um modo de detecção capacitiva acionando um eletrodo de detecção utilizando um controlador. em algumas implementações, um objeto posicionado no ou próximo do eletrodo de detecção pode ser detectado utilizando o sensor de impressão digital no modo de detecção capacitiva, e o controlador pode acionar eletrodos do sensor de impressão digital de forma diferente para configurar o sensor de impressão digital para operar em um modo de detecção ultrassônica. em algumas implementações, um processador de aplicações pode ser instruído a autenticar uma impressão digital do objeto a partir de dados de imagem obtidos quando o sensor de impressão digital está operando no modo de detecção ultrassônica. em algumas implementações, um visor de um dispositivo móvel contendo o sensor de impressão digital pode ser destravado, ou o dispositivo móvel pode ser despertado quando a impressão digital é autenticada.systems, methods and apparatus for configuring a fingerprint sensor to operate in a capacitive detection mode and an ultrasonic detection mode. A fingerprint sensor can be configured to operate in a capacitive sensing mode by triggering a sensing electrode using a controller. In some implementations, an object positioned at or near the detection electrode may be detected using the fingerprint sensor in capacitive detection mode, and the controller may trigger fingerprint sensor electrodes differently to configure the fingerprint sensor. to operate in an ultrasonic detection mode. In some implementations, an application processor may be instructed to authenticate a fingerprint of the object from image data obtained when the fingerprint sensor is operating in ultrasonic detection mode. In some implementations, a display of a mobile device containing the fingerprint sensor may be unlocked, or the mobile device may be awakened when the fingerprint is authenticated.
